How many simultaneous touch events can the iPad handle? Mac and iPhone developer Matt Gemmell found out. The answer points to how collaborative the iPad can be. In his blog, Gemmell wrote how a test program he wrote worked and showed that the iPad can take 11 simultaneous touches. There are a couple of YouTube videos showing the test and results. As I mentioned in a post about the iPad's future roll in business computing, one of the device's strengths is its potential for collaboration in small teams. It can be used by several users simultaneously, passed back and forth, to annotate a document or brainstorm ideas. It's like a whiteboard but up close and personal. Supporting up to 11 touches, we see that the iPad is engineered from the ground up with this capability.
